CASTEBL-CLAMP FOR PAILs.

aof Illinois, have invented certain new and useful Improvements in Caster-Clamps for Pails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as jwill enable others 1) skilled in the art to which it appertains to make and use the'same.

This invention relates to improvements in scrubbing pails, and more particularly to the mounting or support thereof.

of the class mentioned, which carriage shall be both simple andefficient in construction and operation and at the same time adapt-' ed. for'application to pails of diiferent diameters. V

With this andfurther objects in View, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter described and claimed. E v

In the accompanying drawing, Figure 1 is a perspective view of a structure embody- I ing the features of the present invention. Fig. 2 is a transverse vertical section through a part of the clamping band, the section being taken substantially centrally of one of the caster brackets. Fig. 3 is a similar section taken on a plane approximately centrally of one of the underhanging hooks. clamping band and connected parts detached from'the pail.

Referring to the drawing by numerals, 1 40 indicates a pail surrounded adjacent its lower end by a clamping band consisting of sections 2, 2, and adjustable connectionstherefor for varying the diameter of the band by varying the distance between adjacent ends of the several sections. Such adjustable connections may assume various embodiments, a simple and eflicient embodiment being illustrated and consisting of a bolt 3, passed through outstanding eyes 4:, at

0 of adjacent ends of section 2, the bolt being provided with a head at one end engaging one eye, and a nut 5 at the other end engaging the other eye.

jacent eyes. As many sections2 may be employed as required for surrounding the particular pail or receptacle, and it will be seen that the clamping band is thus adaptable to pails of varying sizes within quite a wide range. Each section 2 is provided with a caster bracket supplied with a caster 6 so that when the sections are connected to form a complete band and are tightened about a pail by drawing up on the nuts 5., the pail clamped within'the sections will be supported on casters and thus rendered easy to move about the floor. Each of the caster brackets may consist of a strap bent into U-. The object in view is the provision of an adjustable carriage or support for a pai shape, as indicated at 7, with the intermedlate portion of the U riveted or otherwise fixed to the section 2, andthe outstanding arms of the U apertured to form verticallyalined bearings for the shank or shaft clamping band.

It has been proposed to supply scrubbing pails with mop wringers or wringing apparatus provided with foot levers, and I find it desirable with some of such levers which extendbeyond the pail to provide means for steadying the pail, and in the present construction I employ a caster bracket of somewhat modified. form from that above described, consisting of a strap formed'into a horizontal portion 12, an upright portion 13, an upper horizontaYportion 14, and an inclined portion 15 connecting the upper horizontal portion 14 with the outer end of the lower horizontal portion 12, the inclined portion being formed with a horizontal offsettoward its lower portion. A caster 16 has its shank journaled in the outer part of the horizontal portion 12 and in the offset of portion 15. The upright portion 13 extends from the inner end of horizontal portion 12 and .is formed with an inwardly extending hook 17 spaced above the horizontal portion 12 a distance proportionate to the height required accordingto the form of the other caster brackets employed. A rod 18 is proportion 14, whereby when the parts are in ported against the tendency to tilt in the.

direction of the applied pressure.

the position indicated in Fig. 1, thenut 20 may be threaded upwardly for clamping the parts firmly together, be threaded downwardly, the'hook 19 removed from the upper edge of the pail, and the guiding bracket thus readily removed.

It is to be observed that regardless of the size of the receptacle to which the clamping band may be applied, each section of the band will contribute a support in the form of a caster, so that when the band is in place on any given receptacle, the receptacle is adequately supported whether three sections have been employed or a much greater number, the points of support being increased in number proportionately to the number of sections employed and consequentlyproportionately to the size of the receptacle to be sustained. Each section 2 consists of a strip, preferably of strap metal, and each section may be considered an article of manufacture in itself, and when so considered, to .be complete should be provided with the caster bracket or its equivalentand in most instances with the hook.

It will be observed that the caster bracket which carries caster 16 is constructed to cause the caster to stand out from the reunderhanging ceptacle or pail, so that when the lever of the wringing mechanism is depressed the pail will besteadied, that is will be sup- What I claim is 1. The combination with a pail, of a or the nut 20 may I bracket and having means clamping band adapted to surround the the pail, means for connecting each section to the upper portion of the pail, and a hook extending from each section and underhanging the pail.

2. The combination with a' pail, of a caster bracket outstanding therefrom, a caster of the bracket, a rod having an adjustable connection to upwardly therefrom and formed with pail engaging means at its upper portion, and an underhanging hook extending inwardly from the bracket.

3. The combination with a pail, of a clamping band surrounding the pail, supports outstanding from the band, and a support connected to the pail and band and outstanding therefrom a greater distance than the other supports.

4. The combination with a pail, of a caster bracket outstanding therefrom, a caster journaled in the outstanding portion of the bracket, a rod connected to the of engagement with the upper portion, of the pail, and

means connected with and extending below the bracket adapted to engage the lower portion of the pail for connecting the bracket thereto.
